If you run GNUstep from java, it will always read its process name as 'java'. This is nothing bad, except that all user defaults for java applications would be saved under the name 'java', and mix one with the other. To workaround this, you just need to set the process name of your process at the beginning of your code. Something like:

  (NSProcessInfo.processInfo ()).setProcessName ("myApp");

See question 3. - it's the same problem with the same solution.

JIGS's implementation is - at present - quite deeply dependent on the GNU Objective-C runtime.

In general, JIGS should be as portable as GNUstep and the GNU Objective-C runtime - wherever you can run the GNUstep base library with the GNU Objective-C runtime compiled as shared you should also be able to run JIGS (assuming you have a JDK 1.2 environment). This means once the GNUstep base library is ported (even without working Distributed Objects), JIGS should be ported as well - and if not, at least it should be possible to port it without particular hassle.

This is the theory - in practice, up to now I only have reports of JIGS running on GNU/Linux i386 and GNU/Linux ppc. If you have experiences running (or trying to run) JIGS on a different machine and os, I (Nicola Pero) would be happy to hear about your experience.
